. N E STATES PATENT QFFICE- sunnnr 's. swmson, or nnLn-nvun, club.-

'nannow.

Be it known that I, semi a citizen of the United States, residing atBellevue, in the county of Huron and State of Oh1o, have inventedcertain new. and useful Improvements in Ha1'rows,'of which the followingis a specification, reference being,

had therein to the accompanyingdrawing. This invention relates to newand-useful improvements in agricultural implementsof that type commonlyknown as riding harrows.

In certain sections of the country; where oranges and cotton are raised,it is necessary on account. of the low branches of the orange trees toemploy a low harrow frame for cultivating between the rows of trees, andin.

cultivating cotton it is necessary to employ a high barrow frame so asto permit the same to readily pass over the. plants. As a result, it hasbeen necessary heretofore to employ two forms of harrows for the abovementioned operations.

The principal object of my invention is therefore'to provide a harrow.which includes a main frame and an earth engaging tool which supportsthe frame, and which is adjustably connected relatively thereto, so thatthe height of the frame relative to the ground may be readily varied toaccommodate the implement to either of the uses above noted.

Another object ofthe-invention is to provide an implement of thecharacter described which includes one or more disk gangs that aremounted for horizontal swinging movements upon the frame, and to providemeans for holding each gang at a predetermined angle with respect to theline of draft whereby the gangs Will be caused to throw the earth eithertoward or away from the line of work.

A further object of the inventionis to provide a novel connectionbetween the frame and each gang whereby the angle of the gang may bereadily adjusted with respect to the frame to facilitate forming a hillof any desired angle.

In the accompanying drawings, "there is shown a main frame 5,- which inthisv instance, is formed from a single length of bar metal, bentintermediate its ends to form a base 6, and converging sides 77. A'draft bar 8 has its rear end connected to the base 6 and has its forwardportiondisposed intermediate and connected to the ends of the sides 7'7.An operators seat 9 is mounted upon a suitable standard 10 which issupported upon the rear end of the draft bar 8. While the draft bar 8is" shown as being formed by two spa cedo'parallel bars, it is obviousthat a singleibar may be employed if so desired.

Secured, to the base 6 of the main frame and preferably at either sideof the draft bar 8 is a disk gang A, the disks 11 of each gang being.suitably mounted upon an axle I2. These gangs are adapted to beconnected to the main frame so that said frame may either be disposed inclose proximity to the ground or in' an elevated posit on thereabove,depending of course upon the nature of the work to which the harrow isto be subjected. In order to so connect each gang with the frame, eachaxle 12 is provided with a yoke 13 havin an angular connecting portion14:. This yo e is adapted to be connected to the frame through themedium of a spindle 15, and a socket element 16. The spindle 15 isdisposed in a substantially vertical plane and is provided at its lowerend with a transverseand substantiall angular base 17. The under side ofthe ase 17 is formed with. a longitudinal channel 18 and with acentrally disposed transverse channel 19. The base 17 is formed at eachside of the spindle 1:3, with bolt-receiving openings which arearranged. at right angles to each other. lVlwn it is desired to connectthe gangs A to the frame 5 so that said frame will be in its lowermostposition, the yokes .13 a re disposed in a substantially horizontalplane and the connecting portions 14 thereof are disposed against therear faces of the bases 17 and secured thereto by bolts 20, as isclearly shown in Figs. 3 and 5 of the drawings. \Vhen it is desired toconnect the gangs 14 with the frame 5 so that the frame will be disposedin its elevated position the yokes 13 are disposed in a vertical planeand have their connecting portions 14 disposed against the underfaces ofthe bases 17 and secured thereto by the bolts 20, as is clearly shown inFigs. 2 and 4 of the drawings. It will thus be observed that the socketand spindle constitute a connecting device which is carried by the mainframe, and includes two points of connection arranged at an angle one tothe other, and that the tool is formed with a part, namely theconnecting portion of the yoke, which is adapted to be secured to saidconnecting device at either of said points.

Each socket element 16 is formed with an open ended socket 21 forreceiving a spindle 15, and each element is furthermore formed withopposed laterally extending ears 22-22. One of these cars is pivotallyconnected to the base 6 of the main frame by means of a bolt 23, and theother car is formed with an elongated opening 24 through which passes abolt 25 that is carried by the base 6 and is adapted to hold saidelement in any adjusted position upon its fulcrum 23. It will thus beobserved that by adjusting the bearing element 16 upon its fulcrum 23,the angle of the respective disk gang A, relative to the frame 5 may beaccomplished and as a result, the slope of the hill to be formed or theslope of the irrigating ditches, may be easily obtained.

In order toset the gangs A at any desired angle with respect to the lineof draft, and thereby throw the earth toward or away from the line ofwork, each base 17, is pro. vided with a sectional lever 26, which isdisposed within the longitudinal channel 18 and retained therein throughthe clamping action of said base 17 and yoke 13. This lever extendsbeyond the ends of the base 17 and either end of the lever is adapted tobe connected to one end of an extensible link 27. Each link is pivotallyconnected to an operating lever 28, which is fnlcrumed upon the drag bar8 in advance of the seat 9, and this lever cofiperates with a segment29, which is carried by the drag bar 8, in the usual manner. It willthus be observed that when one end of the lever 26 is connected with thelink 27 the disk-gang A is held at one angle with respect to the line ofdraft, and when the link is connected to the other end of the lever 26,the disk-gang A is held at the opposite angle. The angle of the gang maybe furthermore slightly shifted by the operating lever 28, the amount ofshift being regulated by the throw of the lever 28. The base 6 of themain frame is formed with a series of openings for attaching the socketelements 16 toward or away from the center of the frame. This permitsthe operator to regulate the spacing of the diskgangs to accommodate theimplement to rows of different widths. The draft bar 8 extends inadvance of the main frame 5 and is supported at its front end by a truck29 of any suitable character, although the truck may be dispensed withif desired.

In the embodiment of my invention as shown in Figs. 9, 10 and 11, themain frame 5 is widened by the attachment of extension frame members3030. Each frame member 30 is bent intermediate its ends to form a base31 and an inclined side 32, the former being connected to one side ofthe base 6 of the main frame 5, and the latter being connected at itsforward end-to the draft bar 8 in advance of the side members 7 of saidmain frame. The members 30 are rigidly connected to the main frame 5through the medium of suitable braces 33. The socket elements 16 areadjustably mounted on the bases 31 of said extension members in a mannersimilar to that previously described. ()ne of the sections of the lever26 is withdrawn from its position and is clamped within the transversechannel 19 of the base 17 of the spindle. Attached to the base 6 of themain frame 5 in close proximity to the draw bar 8 are bearing blocksMr-34;, and journaled in each block is a vertical crankshaft 35 havinglaterally extending crank arms 36 and 37, said arms being disposed atright angles to each other. Each arm 37 is pivotally connected to theadjacent hand lever 28 by means of a link 38, and each arm 36 isconnected to a respective section of the lever 26 by means of anextensible link 39. In practice, when it is desired to adjust the angleof either disk-gangA the lever 28 is shifted, and as a result the link38 will rock the shaft 35. The arm 36 of the shaft will, through themedium of the link 39 and the, section of the lever 26, swing thedisk-gang A upon its spindle. This construction is especiallyadvantageous in cultivating between rows which are spaced a gooddistance apart, as will be readily understood.
